Jean is multiplying 6 x 39. She decides to multiply 6 x 30 first, then add on 6 x 9. What property is Jean using to solve the problem? Her procedure would look like this mathematically

Step-by-step explanation:

For a triangle, any 2 side lengths of the triangle must be greatee than the 3rd side.

Given a triangle with side lengths 11, 23 and x,

we have:

Therefore 34 > x and x > 12. => 12 < x < 34.

Answer:

second option

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is

difference of 2 sides < x < sum of 2 sides , that is

23 - 11 < x < 23 + 11, thus

12 < x < 34

Answer:

1. n power of 25

2.x power of 5

Answer: The expression for number of faces of a pyramid =1+n

Step-by-step explanation:

A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .

Its base describe the number of other faces of it.

For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....

So the total number of faces in a pyramid = base + lateral faces

If a pyramid has n sides therefore it give rise to n lateral faces such that

The total number of faces in a pyramid= 1+n .

Answer:

5 tents

Step-by-step explanation:

1 tent = 6 people

x tent = 28 people

Cross product

1 * 28 = 6 * x

28 = 6x

x = 28/6

= 4.67

Approximately x = 5 tents to an whole number

Therefore, he needs 5 tents for 28 people to sleep in

Answer:

  (x, y) = (2, -6)

Step-by-step explanation:

Subtract the first equation from the second.

  (8x -2y) -(5x -2y) = (28) -(22)

  3x = 6

  x = 2

Substitute this into either equation and solve for y.

  8(2) -2y = 28

  8 -y = 14 . . . . . . . . divide by 2

  y = 8 -14 = -6 . . . . add y-14 to both sides

The solution is (x, y) = (2, -6).

I like a graphing calculator for a quick solution to such problems.

Answer:

19657

Step-by-step explanation:

By PEMDAS, we know we have to calculate the exponents first, then multiply the 2, and then subtract the 7³

2*10⁴ = 20000

20000 - 7³ = 19657

Answer: Blue color = 937.5 ml

green color =   525 ml

Yellow color= 37.5 ml

Step-by-step explanation:

Let the quantity of all kinds of paint required to make turquoise paint be 2.5 x(blue), 1.4 x( green), 0.1 x.(yellow).

Total turquoise color required =2.5x+1.4x+0.1x

[tex]\Rightarrow (2.5+1.4+01)x=1.5\\\\\Rightarrow\ 4x = 1.5\\\\\Rightarrow x=\dfrac{1.5}{4}\\\\\Rightarrow\ x=0.375[/tex]  = 1.5 liters  [given]

Blue color = 2.5 x 0.375 = 0.9375 liters = 937.5 ml  [1 liter = 1000 ml]

green color = 1.4 x 0.375= 0.525 l  =  525 ml

Yellow color= 0.1 x  0.375= 0.0375 =37.5 ml

Answer:

x=4

Rows = 24

There are 24 rows each having 16 seats making a total of 384.

Step-by-step explanation:

Part B

Total number of seats = Total of rows* Number of seats in each row

Let the total number of rows be y. The theater has 384 seats and each row has 16 seats. Putting the values

384= y * 16

y= 384/16= 24

There are 24 rows each having 16 seats making a total of 384.

Part A:

Area= length * width

Area 1= 320= 16 *20

Area 2 = 64

64 = 16 x

x= 64/16= 4

Answer:

[tex]\boxed {\boxed {\sf 133 \ degrees }}[/tex]

Step-by-step explanation:

According to the Exterior Angle Theorem, the exterior angle of a triangle is equal to the sum of the 2 remote and opposite interior angle.

[tex]d=a+b[/tex]

In this triangle, angle B is the exterior angle (d). The two interior angles are 68 degrees and 65 degrees ( a and b).

[tex]\angle B=68 \textdegree +65 \textdegree[/tex]

Add.

[tex]\angle B= 133 \textdegree[/tex]

This can also be solved using triangles and supplementary angles.

The angles in a triangle must add to 180 degrees. We have three angles: 68, 65, and an unlabeled angle we can call x.

[tex]68+65+x=180 \\133+x=180[/tex]

Subtract x from both sides.

[tex]133+x=180-133 \\x=47[/tex]

x is on a straight line with B, so they are supplementary and add to 180 degrees.

[tex]47+ \angle B= 180[/tex]

Subtract 47 from both sides.

[tex]47-47+ \angle B= 180-47\\\angle B= 133[/tex]

Angle B is equal to 133 degrees.

the equation doesn't have a solution lol
